Summary
This report evaluates the effectiveness of the National Highway Traffic Safety Administration’s (NHTSA) High-Visibility Enforcement (HVE) model in reducing distracted driving, specifically hand-held cell phone use. While HVE has successfully improved seat belt usage and reduced impaired driving, its application to distracted driving was untested due to the intermittent nature of phone use, which complicates observation and enforcement. The study aimed to determine if vigorous enforcement, combined with targeted advertising, could increase motorists’ perception of citation risk and subsequently reduce hand-held phone usage in two communities: Hartford, Connecticut, and Syracuse, New York. The intervention was conducted over one year in four enforcement waves. The HVE model combined strong existing laws banning hand-held phone use with vigorous law enforcement and targeted media campaigns. The advertising featured the slogan “Phone in One Hand, Ticket in the Other,” depicting crashes and emphasizing enforcement. Law enforcement agencies in both states issued 100 to 200 citations per 10,000 population per wave, exceeding prior year ticketing levels by a factor of approximately 60. Researchers observed 135,714 drivers in Connecticut and 89,826 in New York across 15 sites in intervention areas and control areas (Bridgeport/Stamford and Albany, respectively). Public awareness was measured via surveys at Department of Motor Vehicle offices. The results demonstrated significant reductions in hand-held phone use in both intervention sites. In Hartford, observed hand-held use dropped from 6.8% to 2.9%, a statistically significant 57% reduction, compared to a 15% drop in the control area. In Syracuse, hand-held use decreased from 3.7% to 2.5%, a statistically significant 32% reduction. Control areas also saw reductions, with Albany dropping from 5.0% to 3.0% (40% reduction). Public awareness of the campaign slogan increased significantly, rising from 5% to 54% in Hartford and from 5% to 29% in Syracuse, while control areas saw minimal increases. Awareness of enhanced enforcement also rose significantly in both test sites. Demographic analysis indicated that drivers aged 25 to 59 and male drivers in Syracuse showed the most substantial drops in usage. The study concludes that the HVE model is effective for distracted driving, utilizing techniques such as stationary spotters, targeted checkpoints, and saturation patrols. The findings suggest that repeated enforcement applications are necessary to maintain reductions, as usage varied between waves. Both law enforcement and the public supported the vigorous ticketing approach. The success in Hartford and Syracuse indicates that high-visibility enforcement can quickly change driver behavior regarding hand-held phone use, enhancing the impact of traffic laws.
Key finding
Observed hand-held phone use in Hartford dropped from 6.8 percent to 2.9 percent, a statistically significant 57 percent reduction, versus a 15 percent drop at control sites.
